Whimsical varieties are planted on beds of bulk drainage and gravel. Ideal alpine slides. It is better to do without manure, or root system dies. Digging runs 20 cm.
Areas clogged rhizomes of weeds, forplanting are not suitable. Where there are long drifts, put them is not worth it. This prevents germ and abundant flowering. Location is better to choose the open, but in some varieties of the penumbra as the Valley, Sharoyan feel comfortable. From flower bed arrangement depends on the flowering period. In areas with scattered sunlight, while buds opening is delayed by 10 days Autumn species prefer to grow under the direct rays. The buds are fully disclosed in the sunny weather and only slightly on cloudy days.

They are encouraged to be planted at a distance of up to 15 cm distance between the rows -. 5 cm. The hole is best to pour gravel for drainage. In order to design flower beds flowers planted nearby. However, it must take into account the period of growth at one site. With many years of cultivation on one site without digging better to do planting rare.
seed multiplication method species for the purpose of obtainingplanting material. Before planting in the ground they stratify.

Care is weeding. loosening. two feedings mineral fertilizers in the period of active growth. The first time they were dispersed on the snow. At the beginning of the growing season is permitted to add urea, but if you miss the time, nitrogen is not only stimulate the growth of leaves, but also cause a fungal infection. After flowering poor soils are fed with chemical fertilizers of phosphorus, potassium and small amounts of nitrogen. On rich soils make superphosphate - 25 g per 1 sq.m. Phosphorus is required for abundant flowering and potassium - for healthy follicles. It is important to observe irrigation regime. Excessive moisture roots suffer badly.
